2. SAFETY INSTRUCTIONS
This apparatus has been designed and tested in accordance with Safety Class I requirements
of IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus, and has
been supplied in a safe condition. This manual contains some information and warnings which
mus t be followed by the user to ensure safe operation and to retain the apparatus in a safe
condition.
2.1 INITIAL INSPECTION
Check the contents of the consignment for completeness and note whether any damage has
occ urred during transport. If the contents are incomplete, or if there is a damage, a claim
should be filed with the carrier immediately.
Als o t he loc al Organization o f Philips Weighing has to be informed in order to facilitate the
repair or replacement of the instrument.
2.2 BEFORE COMMISSIONING
2.2.1 General
Bef ore putting the instrument into operation after storage or transport, visually check it for
physical damage.
2.2.2 Mounting
The i ns trument is suitable for panel mounting. Heat influence, such as direct solar radiation
etc., should be avoided. Please observe the required environmental conditions as given in the
technical data.
2.2.3 Dismantling the instrument
When removing the housing, covers or other protecting parts, live parts or terminals will be
exposed.
! CAUTION - DANGER TO LIFE !
The refore setting the switched-on instrument must be performed only by trained personnel
aware of the risks.
2.2.4 Type of protection
The instrument is protected according to class I (protective earth) of the IEC 348 or the
German VDE 0411 regulations.
The connection cable must contain a protective earth conductor which must not be interrupted
ins ide or outside the instrument (e.g. by using an extension cable without protective earth
conductor).
OPERATING MANUAL PR 1612/02, Rel. $$ 2.30 Page: 2 - 2
2.2.5 Connection of supply voltages
The PR 1612/02 can be connected to nominal 110, 128, 220 or 238 V AC.
Upon delivery it is set to 220 V AC . Check whether it is adapted to the local nominal mains
voltage.
For connecting the supply voltage cable (including protective earth or earth conductor) to the
instrument, strictly observe the relevant Operating Manual. As the instrument has no switch,
it will be in operation as soon as the supply voltage is applied.
2.2.6 Earthing
The instrument must be connected to earth by means of a special protective earth conductor
(of the mains cord). The separate conductor must be connected to one of the clamps at the
rear of the instrument.
2.3 REPAIR AND MAINTENANCE
2.3.1 Failure and excessive stress
If the instrument is suspected of being unsafe, take it out of operation and make sure it
cannot be operated inadvertently. This is the case when the instrument
- shows physical damage
- does not function any more
- is stressed beyond the tolerable limits (e.g. during storage and transportation).
2.3.2 Repairs
Caution !
The instruments sold by Philips Weighing are subject to a repair procedure.
In case of defect or malfunction, please contact your local Philips Weighing organization for
the required measures.
Important !
Maintenance or repairs must be performed only by trained personnel aware of the risks (see
chapter 2.2.). Make sure that the construction of the instrument is not altered to the
detriment of safety. Above all, leakage paths, air gaps, and insulation layers must not be
reduced.
2.3.3 Replacing fuses
Replacing fuses is described in part 4.8.
Make sure that only fuses of the required current rating, and of the specified type to IEC 127
are used for renewal. The use of repaired fuses, and/or short-circuiting of fuse holders is
prohibited. Fuses shall only be renewed by a qualified person who is aware of the hazard
involved.
OPERATING MANUAL PR 1612/02, Rel. $$ 2.30 Page: 2 - 3
Warning:
The instrument must be disconnected from all voltage sources when a fuse is to be
renewed, or when the instrument is to be adapted to a different mains voltage.
2.3.4 For special attention
When soldering on the circuit boards it is essential
a. to switch off the power, and
b. to use a low-voltage soldering iron, galvanically separated from the mains side.
Suitable soldering irons should have temperature control and different types of nozzles (pin
point tips), e.g. Weller Magnastat WTCP or WECP, Ersa TC 70/24 V.
If a higher wattage-rating soldering iron is used, excessive heat can cause the printed circuit
tracks to separate from the board base material, thus irreparably damaging the printed circuit
board.
In general, use short time heating with high tip temperature at a small point, avoid long time
heating.
2.3.5 Electrostatically sensitive components
The instrument contains electrical components which are susceptible to damage from
electrostatic discharge. Servicing statically sensitive assemblies or components should be
performed only at an antistatic work station by qualified service personnel.
2.3.6 Battery replacement
This instrument is equipped with lithium back-up batteries. When the battery voltage is below
the specified value, or the batteries are defective, they must be replaced by a trained person,
or by the Customer Support of the local Organization of Philips Weighing. For disposal, the
local regulations must be followed.

4. M O U N T I N G A N D I N S T A L L A T I O N
During the installation of the instruments, some presettings can already been carried out
without the mains supply switched-on.
CAUTION
Before unpacking and operating the instrument,
the safety instructions in Part 2 must be observed
4.1 MOUNTING INSTRUCTIONS
The instrument is suitable for rack and panel mounting, or for table top use.
Taking the different protection classes between front (IP 65) and housing (IP 30) into
account please take care for
- a proper isolation between both parts, and in conjunction with it
- a sufficient stability of the panel.
Mounting is to be done as follows:
- Ioosen the two clamp screws at the rear of the case until the slide clamps can be removed.
- work ing f rom the front o f the panel, insert the indicator with the gasket mounted into the
panel cut-out.
- insert slide clamps back onto the case, push them up tightly against the rear of the panel,
and fix them by means of the two clamp screws. Do not overtighten them.
- position connectors and cables as required.
OPERATING MANUAL PR 1612/02, Rel. $$ 2.30 Page: 4 - 2
4.2 OPENING THE INSTRUMENT
• disconnect the instrument from the mains and all power sources,
• carefully remove the 6 self tapping screws at the rear panel of the instrument and keep
them safely,
• pull out the inner unit from the housing carefully.
4.3 SWITCHING ON THE BACK-UP BATTERY
The PR 1612/02 is equipped with a lithium
back-up battery for its RAM. It is switched
off upon delivery.
In order to save the data of the RAM
after having put the PR 1612/02 into
operation, the battery must be switched
on by closing solder link BAT on the
main board before calibration.
Refer also to part 5.5.2.
4.4 CONNECTION POSSIBILITIES
All connection facilities are located at the rear of the instrument.
OPERATING MANUAL PR 1612/02, Rel. $$ 2.30 Page: 4 - 3
4.5 CONNECTION OF MAINS AND SUPPLY VOLTAGES
The PR 1612/02 is connected to the mains via the 3 -pole connector at the rear of the
instrument.
Please note that the instrument has no mains switch, and therefore, is ready for operation as
soon as the mains is connected.
The instrument operates at mains voltages of 110,128, 220 and 238 V AC and 50/60 Hz.
Upon delivery it is set to 220 V AC.
For changing of voltage, proceed as follows:
- disconnect the power,
- solder links on the transformer bobbin according to the following figure,
- replace the mains fuse inside the connector.
4.6 REPLACING FUSES
Before replacing fuses observe and follow the relevant safety instructions at para. 2.3 of this
manual .
The instrument is protected by means of a mains fuse which is located in the mains socket as
shown below.

OPERATING MANUAL PR 1612/02, Rel. $$ 2.30 Page: 4 - 4
4.7 INSTALLATION INSTRUCTIONS FOR CONNECTING DATA CABLES
All cables transferring measuring
data and control signals must be
kept away from power cables and
should be screened.
The screen must be connected
to the housing of the connector
(see fig. below), or to the clamps
at the rear plate.
Relays and circuit breakers connected to the weighing system have to be spark suppressed as
follows:
- AC relays by means of an R-C combination (R = 100...300
parallel and as near as possible to the relay coil;
- DC relays by a reverse biased spark suppressing diode (e.g. BYX 10) connected in reverse
direction and in parallel and as near as possible to the relay coil.
